IMPROVED APPARATUS FOR. DISTILLING- SPIRITS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Beit known that I, ELI D. BANNISTER, of St. Louis, in the county of St. Louis, and State of Missouri, have invented a new and useful Apparatus for Distilling Spirits; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being `had to the accompanying drawings, -and to the letters of reference marked thereon.

. The object of this invention is to produce pure spirits by a single passing of such spirit-extracts once through the still; and

It consists in the special arrangements of the still and heaters with relation to each other and their connecting-pipes, and their manner of operation.

In the production of pure spirits, by distillation, it has been heretofore a dithcult matter to separate, and keep apart from the pure spirits, what is 'termed fuseloil.

The fusel-oil is an active poison, and if allowed in the pure spirits, in solution, is quite as deleterious as `when separate, and in fact, the complete separation of this oil from the spirits has almost baiedrthe skill of the chemist.

rlo enable others skilled in the art to make and use my invention, I will proceed to describe the same.

In the drawings- A represents a common still, in which themash to be distilled is placed, and into which passes steam-pipe b, as in ordinary stills.

B represents a heater, which -is partly illed with water.

G represents a doubler, and

D, the worm-tub.` i

The charge to be distilled is run into still A, by means of pipe a, from the mash-tub, and the steam is then introduced through pipe b, which heats lthe contents of the still, and vaporizes the spirits contained therein, which then passes through 'pipe c into heater B, which is the only channel open for such vapor to pass.

Heater B is heated to the temperature sufficient to vaporize spirit, by means of pipe c or steam-pipe k and the vapor will pass from heater B into doubler C, through pipe d, which -is the only means of egress for such vapor, and from doubler C, through pipe e, into `worm-tub D, where it is condensed; and the spirit makes its exit at c.

Heater B is supplied with water, by means of pipe j', from tub D.

A represents a condenser, which is lpartly lled with water. v The vapor from still A passes into condenser A', through pipe g, which must, in all cases, have its discharge below the surface of the water in A'.

Pipe h is used to discharge the contents of A into heater B.

'i is a safety-pipe between A and B, for the vapor that may accumulate in A to pass into heater B.

Water is supplied to condenser A' by means of pipe j.

l is a discharge-pipe from heater B back into still A; and

l is another pipe to discharge the low spirits into heater B; and Y o is a discharge-pipe for still A; and

m is the discharge-pipe for steam, when steam-pipe 7c is used to heat the contents of B.

The pipe c passes from the top of the still A to nearly the bottom of heater B, at all events; and in every case, it must be below the water-surface in the heater B.

'Ihe spirits, in vapor, pass through pipe c direct into the water in heater B, by which process the` fusel-oil will rise to the surface of the water, and the other properties will mix with the water.

Heater B is then heated, by any means, to a degree that will vaporize the spirits, and not the water and fusel-oil, which are left in heater B, to he discharged through `pipe l, while the pure spirits, in vapor, pass oft' through pipe d into doubler O, and so through the worm-tube to discharge n.v

The pipe g conducts the vapor from still A into and below the surface of the water, shown in blue in A', where the spirit receives a water-bath, and is then conducted into heater B, through pipe h, but the fusel-oil does not pass into the heater B with the spirit, but is retained upon 'the surface of the Water in A until purposely discharged through pipe h into -heater B, and from heater B into still A, where all the essential qualities, if there be any, are vaporized and pass into A', when the oil and impurities are discharged by pipe o, thus entirely separating the poisonous oils from the spirits, at a single operation, and producing a pure spirit, in every Way improved in quality.

The still, heaters, and tubes, are constructed in the usual manner, of metal; sheet-copper being preferable,v but any of themetals that will answer the purpose'may be used, and can be made of any capacity desired.-

To condenser A and heater B are attached a watergauge and thermometer, which will, at all times, show the height and temperature of contents inside thereof.

The drain and discharge-pipes have stop-cocks, conveniently placed thereon, as well as in connecting-pipes c and I angl aware that the process of condensing the alcohol-vapor in water, for removing impurities, has been in use, and is described in patent, No. 61,388. Such manner of introducing the vapor into the Water, as therein described, I do not claim; but having thus described my invention,

What I claim, and desire to secure by Letters Pat ent isl. The condenser A', when connected with the still,

in the manner and for the purpose substantially as described.

2. The combination of the still A, condenser A', and beater B, with the doubler C and Worm-tub D, for the purpose substantially as described.

3. The distilling of spirits,v by means of still A, heater B, doubler O,- and Worm-tub Dlsubstantially als described.

4. The condenser A', containing water, the manner of conducting the vaporized impure spirits into A', and below the surface of the Water, and the discharging the spirits into'heater B, after receiving the water-bath, substantially in the manner and for the purpose described.
